Abstract

Cover for a hygiene or care article, having a web-shaped section and a fastening section with the aid of which the cover can be fastened to the hygiene or care article.

Description

The present invention relates to a coating for a hygiene or care article according to the preamble of claim 1.

Hygiene or care articles are known from the prior art. They are usually shipped as pre-packaged, sterile packaged products that are removed from the packaging and then used. Because of sterility, such products can not be modified prior to use, so desired additional functionality is generally not incorporated into the product can.

The object of the present invention is therefore to expand the possibilities of use and the functionalities of existing hygiene or care articles.

DETAILED DESCRIPTION OF THE INVENTION

This object is achieved by the wound covering article according to the main claim. Further preferred embodiments are given by the features of the dependent claims.

Accordingly, a cover for a hygiene or care article is provided, comprising a web-shaped portion and a fixing portion, by means of which the cover can be attached to the hygiene or care article.

• • Elastischer Bund
• • Klettband oder mit einem Klettband verbindbares Flauschband
• • Klebeband
• • Knopf, bevorzugt Druckknopf
• • Magnetverschluss
• • Reißverschluss

aufweist. Der Elastische Bund ist bevorzugt in Form eines Plissees ausgestaltet. Auf diese Weise kann der Bezug ähnlich wie ein Spannbettlaken an dem Hygiene- oder Pflegeartikel angebracht werden. It is preferably provided that the attachment section contains at least one agent selected from the group

• • Elastic waistband
• • Velcro tape or loop tape that can be connected with a Velcro strip
• • Duct tape
• • Button, preferably push button
• • magnetic closure
• • Zipper

having. The elastic waistband is preferably configured in the form of a plisse. In this way, the cover can be attached to the hygiene or care article similar to a fitted sheet.

Preferably, it is further provided that the cover is placed in the form of a coating over the hygiene or care article.

Particular preference is further provided that the cover is attached to one side of the hygiene or care article.

• a) der Bezug kann bei durch Flüssigkeitsaufnahme des Hygiene- oder Pflegeartikels bedingter Volumenzunahme desselben dieser Volumenzunahme folgen, so dass er letztere nicht behindert.
• b) der Bezug kann für Hygiene- oder Pflegeartikel verschiedener Größe verwendet werden. So ist beispielsweise die Verwendung für einen quadratischen Hygiene- oder Pflegeartikel mit den Außenmassen 8 × 8 cm oder 12 × 6 cm denkbar.

Likewise, it is preferably provided that the cover comprises an elastic material. Said elastic material can be produced for example by doping the coating material with elastic yarn (rubber, latex, spandex or the like). Due to the elasticity two things can be achieved:

• a) the reference can follow in the same case of liquid intake of the hygiene or care article volume increase of the same volume increase, so that he does not hinder the latter.
• b) the cover can be used for hygiene or care articles of different sizes. Thus, for example, the use for a square hygiene or care article with the outer dimensions 8 × 8 cm or 12 × 6 cm is conceivable.

• • Alginat
• • Modifizierte Cellulose, bevorzugt Alkylierte Cellulose, besonders bevorzugt carboxyalkylierte Cellulose, besonders bevorzugt Carboxymethylcellulose
• • Nylon oder Polypropylen
• • Zellulose oder modifizierte Zellulose
• • Flüssigkeitsleitende Fasern
• • Offenzelliger Schaum, bevorzugt aus PU, und/oder
• • Seide

aufweist.Particularly preferably, it is further provided that the cover contains a material selected from the group

• • Alginate
• Modified cellulose, preferably alkylated cellulose, particularly preferably carboxyalkylated cellulose, particularly preferably carboxymethylcellulose
• • nylon or polypropylene
• • cellulose or modified cellulose
• • Liquid-conducting fibers
• Open cell foam, preferably of PU, and / or
• • silk

having.

All of these materials have particularly favorable properties in terms of wound healing promotion, fluid management or atraumatic.

Modified cellulose is understood in particular to be viscose ("modal"), mercerized cotton or lyocell ("tencel"). All these materials are very kind to the skin and sometimes have liquid-conducting properties.

The term "liquid-conducting fibers" means in particular those synthetic fibers that dry quickly and do not store moisture in the fiber but pass it on. These fibers are preferably made of polyester or polyamide or a mixture of these two substances. Such 'fibers are also used in sportswear.

Preferably, it is further provided that the cover comprises a heavy metal in elemental or ionic form, preferably selected from the group consisting of copper, zinc and / or silver.

Preferably, said heavy metal is used on the side facing the wound.

In addition to the heavy metals present in elemental form, these definitions generally also include their salts, preferably their chlorides, sulfates, sulfides, sulfites or nitrates, their organometallic compounds or their sulfonamide compounds (such as silver sulfadiazine).

The antimicrobial properties of silver or silver ions are known to the person skilled in the art and need not be discussed further here.

• 1) Da sie hoch redoxaktive Metallionen darstellen, fördern sie die Peroxidation von Membranlipiden und beschädigen dadurch die Zellwand des Mikroorganismus. In dieser Eigenschaft bewirkten sie zudem eine Verschiebung der essentiellen Metalle von ihren ursprünglichen Bindungszentren und stören so den Stoffwechsel des Mikroorganismus.
• 2) Sie beschädigen das genetische Material des Mikroorganismus, indem sie die DNA binden und somit ihre Konformation ändern
• 3) Die beschädigen die Proteine des Mikroorganismus, insbesondere bewirken sie einen Abbau von Sulfhydrylgruppen sowie eine Oxidation bestimmter Aminosäurereste.
• 4) Sie beeinträchtigen die oxidativen Phosphorylierung und stören das osmotischen Gleichgewicht.

Copper or copper ions deactivate or kill a broad spectrum of viruses and microorganisms most efficiently. In this case, copper or the copper ions acts in different ways.

• 1) Since they are highly redox-active metal ions, they promote the peroxidation of membrane lipids and thereby damage the cell wall of the microorganism. In this capacity, they also caused a shift of the essential metals from their original binding centers and thus disrupt the metabolism of the microorganism.
• 2) They damage the genetic material of the microorganism by binding the DNA and thus changing its conformation
• 3) damage the proteins of the microorganism, in particular they cause degradation of sulfhydryl groups and oxidation of certain amino acid residues.
• 4) They impair the oxidative phosphorylation and disturb the osmotic balance.

In addition, copper or copper ions influences the different biological defense mechanisms of the microorganism in such a way that resistance to antimicrobial agents is practically no longer present. Incidentally, the same applies to zinc.

• • Chemische Gasphasenabscheidung (CVD)
• • Flammenbeschichtung (C-CVD)
• • Physikalische Gasphasenabscheidung (PVD) Plasmagestützte Chemische Gasphasenabscheidung (PECVD) Rotationsbeschichtung (spin coating)
• • Spritzen
• • Tauchbeschichten (Dipcoating)
• • Vakuumverdampfen
• • Sputtern

It is furthermore preferably provided that the elemental or ionic heavy metals are applied by coating to a carrier material. The carrier material may be, for example, a film, a granulate, a fiber or a yarn. Preferred coating methods are, for example:

• • chemical vapor deposition (CVD)
• Flame coating (C-CVD)
• • Physical Vapor Deposition (PVD) Plasma-assisted Chemical Vapor Deposition (PECVD) Spin Coating
• • spraying
• • Dipcoating
• • Vacuum evaporation
• • sputtering

The person skilled in the common methods are known, and he is therefore able to apply without further inventive step, the above-mentioned method for coating the primary dressing according to the invention with elemental or ionic heavy metals.

Correspondingly coated with silver materials are, for example, from the applications US6861570 . US6087549 . US7005556 . US7214847 , and US7230153 known. However, at no point do they mention the synergistic benefits associated with superabsorbent polymers.

The coated film or fiber or coated granules or yarn is then further processed into said sheet-like component. In the case of granules, this can be done for example by extrusion, in the case of the fiber or the yarn by spinning and then felting, weaving, knitting or knitting.

Furthermore, it is preferably provided that the elemental or ionic heavy metals are incorporated by coextrusion in a carrier material.

In this case, the elemental or in ionic form of the present shear metals, for example in the form of colloids, in the form of salts (preferably as chloride, sulfate or nitrate) or in the form of organometallic compounds in the extrusion process can be introduced.

It is further preferred that the heavy metals present in the elementary or ionic form are present in filament or fiber form and, if appropriate, are processed with a further material to form a sheet-like material.

This is especially intended for spinning and subsequent felting, weaving, knitting or knitting. This may optionally be used in combination with other fibers or yarns, e.g. Polyester, polyamide, elastic yarns etc. take place.

In addition, the at least one elemental or ionic heavy metal may be supplemented by calcium phosphate (for example in the form of calcium phosphate nanoparticles coated with silver, zinc or copper). The combination of one of the three heavy metals with calcium phosphate is up to 1000 times more deadly than conventional silver preparations for many germs. A crucial factor seems to be that bacteria use the carrier calcium for their metabolism. The 20 to 50 nanometer calcium phosphate particles are taken up by the microorganisms as food and thereby decomposed. Thousands of 1 to 2 nanometer small silver particles are released and unfold their bacteriostatic effect.

• • Silikonnetz oder -Gitter
• • Dreidimensional perforierte Folie, und/oder
• • Wundgaze

Furthermore, it is preferably provided that the cover has a wound spacer grid at least in sections. Said wound spacer grid is preferably at least one selected from the group comprising:

• • Silicone net or grid
• • Three-dimensionally perforated foil, and / or
• • wound gauze

The term "wound distance grid", a lattice or gauzy structure that - often as a so-called "primary dressing" - is applied directly to a wound before, if necessary, a secondary dressing is applied. Wound distance screens are often referred to as "wound gaits" and serve primarily to prevent the entire wound dressing from sticking to the wound. For this purpose, wound spacer mesh are made of a material or coated with a material that reduces or prevents adhesion to the wound. Alternatively, the geometry of the wound distance grid can also be designed such that adhesion to the wound is reduced or prevented. Preferably, these are gauzes made of a nylon material or so-called Fettgazen. These may preferably have a hexagonal or triangular mesh pattern.

Commercially available examples of wound spacer meshes are e.g. the products "Mepitel" (silicone-coated, elastic polyamide mesh), "Physiotulle", "Urgotül" (network of polyester fibers soaked with hydrocolloid particles and vaseline) and "ADAPTIC" (smooth viscose knit, impregnated with an oil-in-water emulsion).

The aforementioned products are two-dimensional wound spacer meshes, which therefore essentially take the form of a gauze or a mesh. A three-dimensional wound distance grid is known under the name "sorbion plus" and especially in the EP2004116 the assignee of the present invention, the contents of which are fully incorporated herein by reference.

Such a three-dimensional wound spacer grid has a liquid-permeable, pliable material section made of a thermoplastic, which has a first, smooth surface, a surface facing away from the smooth surface and a second rough surface. The latter is produced by a multiplicity of three-dimensional perforations, the walls of which protrude from the first, smooth surface and each run out into a free-edge edge projection, giving the second surface a rough grip.

The perforations are made by punching inserted on one side. This creates a rough side with overhangs and a more or less smooth side.

The material has, as the Applicant has shown, extremely good binding properties for pathogens, and complements so well with the properties of the superabsorbent, which also has a binding capacity for bacteria.

With its rough side towards the wound, the material also has excellent debridement properties. In this way, the material helps break up biofilms and bind the released pathogens.

A wound distance grid reliably prevents sticking of the hygiene or care article to the wound and wound edge maceration. Therefore, unlike the foams known from the prior art, the said active element no longer has to be tailored to the shape of the wound, which considerably reduces the workload of the medical staff.

Preferably, the wound distance grid is coated with a heavy metal in elemental or ionic form, preferably selected from the group comprising copper, zinc and / or silver, or it contains such a material as a constituent.

Said hygiene or care article is preferably an article selected from the group consisting of wound care articles, sanitary napkins, tampons, incontinence articles, diapers, medical underpads, stoma bag inserts, floor mats, surgical drapes, handkerchiefs and / or hyperhidrosis articles.

Preferably, it is further provided that a water-impermeable backsheet is provided, which is at least partially attachable to a region which is released from the inventive cover.

Said backsheet can be attached to the cover or the wound or care article with Velcro straps, snaps, adhesive tapes or the like. It preferably consists of a liquid-impermeable material and ensures that absorbed wound fluid does not escape to the outside.

Furthermore, it is preferably provided that the hygiene or care article is a wound care article.

In the following, the term "wound care article" is intended in particular to designate a wound dressing, preferably a flat wound dressing or a wound care cloth intended for the human, dental and / or veterinary sector.

Said wound care article may preferably be in the form of a swab, a wound wipe, a wound dressing, a wound compress, a wound pad, an optionally elastic wrap, a bandage, a plaster or a stocking.

In particular, the term "wound care article" may also be understood as an ensemble of various products placed in a given arrangement on the wound to be treated. This ensemble can form a physical unit by the various products are combined in a common shell or - if necessary, without a shell - are adhesively bonded together. However, the ensemble may also be in the form of a kit in which the various products are optionally placed on the wound to be treated by means of a wrap, adhesive tape, adhesive tape or patch in the given arrangement.

It is particularly preferred that the wound care article has an absorbent body comprising superabsorbent polymers.

Superabsorbent polymers (SAP) based on acrylates are plastics that are able to absorb many times their own weight - up to 1000 times - in liquids. Chemically, these are, for example, copolymers of acrylic acid (propenoic acid, C ₃ H ₄ O ₂ ) and sodium acrylate (sodium salt of acrylic acid, NaC ₃ H ₃ O ₂ ), it being possible for the ratio of the two monomers to vary from one another. In addition, a so-called core crosslinker (core-crosslinker, CXL) is added to the monomer solution, which connects the long-chain polymer molecules formed in places with each other by chemical bridges (they "crosslinked"). These bridges make the polymer water insoluble. When water or aqueous salt solutions penetrate into the polymer particles, it swells up and tightens this network at the molecular level so that the water can no longer escape without help. The superabsorbent polymers can be present in the hygiene or care article according to the invention in the form of granules, a powder, a bed, a compact, a foam, in the form of fibers, a Fasergewirkes, random or fleece and / or a fiber wadding.

Alternatively, the superabsorbents may be based on methylacrylic acids, acrylamidopropanesulphonic acid copolymers, starch-acrylic acid graft polymers, vinyl acetate-acrylic acid ester copolymers, acrylonitrile or acrylamide copolymers.

It is further preferred that the absorption body comprises a nonwoven in addition to a proportion of superabsorbent polymers.

The absorbent body may preferably comprise a substantially flat absorbent body of absorbent material consisting of an absorbent web having superabsorbent polymers dispersed therein. These may be in the form of a granulate, a powder, a bed, a compact, a foam, in the form of fibers, a Fasergewirkeses, -laid or -fleece and / or a fiber wadding.

In this case, the absorbent body has at least one material which is selected from the group comprising a mat, in particular an airlaid of said yarns or fibers of superabsorbent polymers with incorporated superabsorbent polymers, and / or a loose filling of superabsorbent polymers. Said Airlaid mat may preferably have a substantially flat material portion of absorbent material, the z. B. consists of an absorbent fleece of said fibers with superabsorbent polymers distributed therein.

This absorbent body may correspond to the absorbent pad which is contained in a wound dressing of the applicant of the present invention, as described, for example, in US Pat WO03094813 , of the WO2007051599 and the WO0152780 and sold under the trade name "sorbion sachet". The disclosure of the said writings is fully attached to the disclosure of this document.

In another embodiment, the absorbent body can also form a core which - possibly flake-like - fibers or yarns of superabsorbent polymers and superabsorbent polymers in granular form, wherein the granules are glued or welded to the fibers or yarns in several heights, and the granules are distributed over more than 50% of the total height of at least a portion of the core, wherein there are mixed areas of granules and fibers. The proportion by weight of the superabsorbent polymers may preferably be in the range between 10-25% by weight. Similar constructions are known from conventional incontinence materials and known as sanitary napkins for their cushioning properties. Around said core may be disposed a sheath which is overlapped in areas and which may be e.g. an adhesive seam is covered or part of the same.

The absorption body particularly preferably has a fleece, preferably a nonwoven or airlaid, which consists of superabsorbent fibers ("SAF", preferably polyacrylates) or contains these as constituent. The fibers can, for example, with fluff pulp (cellulose) or with Be mixed polyester fibers. Alternatively or additionally, a layer structure may be provided.

The absorbent body, in another embodiment, may also include at least one flat layer comprising fibers or yarns of superabsorbent polymers to which superabsorbent polymers in granular form are adhered. This results in a preferred embodiment, a structure of the body having at least two layers, wherein at least one cover layer underlays a layer having superabsorbent polymers. Optionally, a second, flanking cover layer may be provided.

In another embodiment, the absorption body may have at least one cover layer of a sheet-like material, preferably a nonwoven material, onto which superabsorbent polymers in pasty or amorphous form are applied, preferably with an adjuvant. This also results in a structure of the body having at least two layers, wherein at least one cover layer underlays a layer having superabsorbent polymers. In this case, very high proportions by weight of superabsorbent polymers can be achieved. Optionally, a second, flanking cover layer may be provided.

In the two aforementioned embodiments, there are no mixtures of fibers and superabsorbent polymers in the plane; but only fixed announcements of both materials. The optionally provided multiple layers can be physically compacted together by rolling, pressing, calendering or similar processes in a preferred embodiment.

It is particularly preferred that the absorbent body in its construction corresponds approximately to the commercially available products "sorbion sachet", "Tenderwet", "Zetuvit", "Drymax", "Vliwasorb" and / or "Curea P".

The cover furthermore preferably has an adhesive area at least in sections. Said adhesive area may comprise a physiologically acceptable adhesive, for example, acyl, hydrocolloid or silicone based.

Preferably, it is further provided that the cover at least partially has a pattern of incisions and / or punches.

The term "incision" as used herein refers to an incision in the cover in which no material has been removed. The term "punching" as used herein refers to an incision in the A reference where material has been removed.

Incisions in the context of the present invention are preferably incisions in the material without the material being substantially removed. Said incisions may be slotted or angular (L-shaped), but also cross-shaped or star-shaped. Punches in the context of the present invention are characterized by a substantial removal of material and are preferably circular ("punched holes"), diamond-shaped, or polygonal. Of course, combinations of incisions and punches in a reference are conceivable.

It is important that the shape of the incisions and / or punches, or their depth, can be specified by the relevant punching or incision tool.

It is preferably provided that the incisions and / or punches are designed and / or arranged in such a way that they increase the softness, the conformability and / or the wearing comfort of the cover. Likewise, it is preferably provided that the incisions and / or punches are formed and / or arranged in such a way that they facilitate the liquid entry into the hygiene or care article.

Further provided is a kit of parts comprising a cover according to one of the preceding claims and a hygiene or care article as sketched in the present description. Such a kit may consist of at least two separate sterile-packaged individual products. However, it can also consist of at least two products in one and the same sterile packaging.

Furthermore, the use of a cover according to one of the preceding claims is provided according to one of the preceding claims in a vacuum wound care system.
